clustering the coordinates of the voxels in the 3D complex image representing multiple seats within the vehicle cabin into one or more clusters;
associating each cluster with a different seat in the vehicle;
analyzing the clusters to determine presence of one or more occupants inside the vehicle; and
using geometrical data of the vehicle regarding the position of the different seats to determine which seats in the vehicle are occupied.
